Hi I'm posting from iugg , where I've just seen David Mitchell and later A Cirisan
David proposed seeding Cirrus clouds in warm, supersaturated air, as the resulting ice crystals grow and rain out, drying the air and this preventing stable Cirrus forming if the air mass cools further. He proposed using chemical seeding methods, as opposed to the liquid air previously discussed on this list. I've copied him in, so hopefully he will reply all with more info. This concept is interesting, as it raises the issue of similar seeding effected by fallout of SRM sulphur particles. Cirisan tested SRM considered this seeding of Cirrus and consequential precipitation triggered by SRM particle fallout and found this offsets about 1 pc of agw in n hem. Useful benefit but not esp useful. Perhaps it could be leveraged further? A -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
